ATM Self Routing Switch Element

The SRE is a 4x4 cell-switch building-block, which can be used as the basis for a variety
of 155Mbps ATM switch fabrics. Although various interconnection topologies can be used,
the SRE is ideally suited to the construction of compact matrices due to its row and column
expansion ports. These provide re-timed, buffered outputs to simplify device
interconnection.
Other key features are:

Support for FECN/BECN congestion control based on internal queue fill-levels
